[QUOTE="EddieS'04, post: 994185, member: 61136"] Take the free muffler. Sell it to make up some of your cost. I would go with the 3" hushpowers, 3" Y into single out 3". The Roush 2 1/2" tip inlet can be cut and machine expanded to 3". 3" single exit should take care of the back pressure. The hushpowers are a flat oval glass pack, straight thru. The other choice is do true duals, smaller pipe with a right side bumper cutting. For a second roush tip. What size tubing are you using on your single system now? IMO, larger tubing or duals. 11psi has to go some where. [/QUOTE]
